Browns® Tropical Carnival® Zoo-Vital® Extruded Daily Diets provide superior, healthy nutrition in every bite. Seed based diets allow birds to be selective eaters and miss out on key nutrients. Since 100% of each pellet is edible food, birds get all the nutrition from each pellet consumed. The extrusion process used to create these pellets helps control unwanted contaminants that may be found in raw seeds, grains, fruits and vegetables.
